Descriptions
Race condition in the ssl_parse_serverhello_tlsext function in t1_lib.c in OpenSSL 1.0.0 before 1.0.0n and 1.0.1 before 1.0.1i, when multithreading and session resumption are used, allows remote SSL servers to cause a denial of service (memory overwrite and client application crash) or possibly have unspecified other impact by sending Elliptic Curve (EC) Supported Point Formats Extension data.
Condición de carrera en la función ssl_parse_serverhello_tlsext en t1_lib.c en OpenSSL 1.0.0 anterior a 1.0.0n y 1.0.1 anterior a 1.0.1i, cuando multihilos y la redención de la sesión están utilizados, permite a servidores SSL remotos causar una denegación de servicio (sobrescritura de memoria y caída de la aplicación del cliente) o posiblemente tener otro impacto no especificado mediante el envió de datos Elliptic Curve (EC) Supported Point Formats Extension.
A race condition was found in the way OpenSSL handled ServerHello messages with an included Supported EC Point Format extension. A malicious server could possibly use this flaw to cause a multi-threaded TLS/SSL client using OpenSSL to write into freed memory, causing the client to crash or execute arbitrary code.
